The main aim of this study was to provide relevant knowledge to the understanding the supply of water in Masaka municipality, considering the quality of water supplied in parameter of turbidity. Involved also are the specific objectives of the study which include finding out the trend of water supply in Masaka district, to study the turbidity of water supplied by National Water and Sewerage Corporation in Masaka municipality, to find out the seasonality of water supplied in Masaka municipality. The methods that were used to analyze the data include the Pearson’s test statistic used to test for trend in turbidity of water supplied by both Boma and Bwala plants. Seasonality of water supplied has also been tested using the Kruskal Wallis’ test under the multiplicative model. Microsoft excel was used to draw the figures. The association between water supplied and turbidity of water was presented on a scatter plot using SPSS software. The findings of the study as regards the relevant knowledge to understanding water supply and turbidity of water in Masaka municipality show that; NWSC procured chemical dosing plants and budgeted for the distilling boat to maintain and improve on the quality of water supplied. NWSC as well procured two standby generators and constructed two elevated 100 m3 water reservoirs and budgeted for two compressors and two high lift water pumps to ensure potable and increased piped in the area. However there are also challenges facing especially the production department and these include; failure of payment of water bills by customers, meter, valve and chamber vandalization and theft, pipe cuts by excavators, road constructors and cultivators, compensation of people with little funds, excavation of hard rocks. In conclusion therefore the study found that there was no trend in turbidity of water supplied by both Boma and Bwala plants and this was significant at 5% level as shown in tables 1 and 2 respectively. The trend of water supplied is shown in figure 1 showing the slight increases and decreases in the supply oscillating between 150,000 m3 and 200,000 m3. Tests for seasonality show that there is no seasonality in supplied water, this was also significant at 5% level. Figure 2 gives the relationship between the supplied water and turbidity of the water supplied in Masaka municipality. Some of the recommendations put forward drove to the need to prevent NRW losses and protect precious water resources which are very important since globally, on average 34% of pumped water ends up as NRW, according to the International Energy Agency. In conclusion, the recommended area for further study is: An analysis of water supplied in other quality parameters that is to say alkalinity, hardness, temperature et cetera.
